THE COST OF OWNING PUBLIC WORKS EQUIPMENT

COSTES DE PROPIEDAD PARA MAQUINARIA DE OBRAS PUBLICASI

The hourly cost of machines may be divided into fixed costs and variable costs. To the category of fixed costs, termed ownership costs, are those which are independent of the fact that the machine is working or not. The fixed costs may be furthermore divided into costs of amortisation, interest on capital and insurance, taxes etc. In the study it was necessary to obtain a high degree of precision as well as a resolution as rapid as possible. These are the reasons for the adoption of the linear amortisation method and for the cost of amortisation, and a chart is given which makes immediate calculation possible. For the determination of the costs arising from interest on capital, the method of mean investment is adopted, with an interest rate of 80%. Insurances and taxes being costs which depend directly on the cost price, can be considered as a percentage of the latter. (TRRL)
